What is the impact of higher bearing revolutions on bearings?

Author:


The higher the bearing speed, the impact on the bearing is mainly reflected in the following aspects:

1. Friction and heating: with the increase of rotational speed, the rolling friction and sliding friction inside the bearing will increase, resulting in an increase in friction speed, resulting in more heat. This increase in heat may not only increase the bearing temperature and affect the lubrication effect, but also accelerate the wear and fatigue of bearing materials.

2.Lubrication problem: high speed may cause the base oil of the grease to evaporate and dry, and the oil film becomes smaller, which in turn affects the lubrication effect of the bearing. Poor lubrication will aggravate the wear and vibration of the bearing, and may even lead to bearing failure. In addition, high speed may also cause grease to be thrown out of the bearing, further worsening lubrication conditions.

3. The influence of centrifugal force: at high speed, the centrifugal force of the bearing rolling body increases, which may lead to changes in the relative position between the internal parts of the bearing, affecting the normal operation of the bearing. At the same time, the centrifugal force may also cause the deformation of the bearing and reduce its stiffness and bearing capacity.

4. Noise and vibration: bearings with high speed are prone to produce greater noise and vibration, which not only affects the overall performance of the equipment, but also may affect the working environment and the health of users.

Therefore, when selecting and using the bearing, it is necessary to fully consider the influence of the rotational speed on the bearing to ensure that the bearing can work normally in the appropriate speed range. At the same time, for high-speed bearings, more stringent lubrication, cooling and maintenance measures are needed to prolong their service life and ensure the stable operation of the equipment.
